Police are "treating the death as unexplained but there were no suspicious circumstances."

The singer's publicist also issued a statement, via the BBC: "It is with great sadness that we can confirm our beloved son, brother and friend George passed away peacefully at home over the Christmas period. The family would ask that their privacy be respected at this difficult and emotional time. There will be no further comment at this stage."

George Michael sold more than 80 million albums worldwide. While in Wham!, the singer scored hits in the early-to-mid '80s with songs like "Wake Me Up Before You Go-Go," "Careless Whisper" and, ironically, "Last Christmas." He continued to have success in his own right as a solo singer with dozens of hits, including "Faith," "I Want Your Sex," "Freedom! '90" and "One More Try."

His iconic 1987 debut album, Faith — which turns 30 in 2017 — won the Album Of The Year GRAMMY Award in 1989.

Back in 2004, George Michael was named "the most played artist on British radio" by the Radio Academy. "I can't believe it. I've only made six albums in 22 years so I don't know how this happened. I'm the luckiest writer on earth," he said at the time.

His sixth and final solo album, Symphonica, was released in March of 2014.
